WINDOW-SHADE.

To all whom it may concern:

Be it known that I,JAMEs R. BARNARD, a citizen of the United States, residing "at Denver, in the county of Denver andState of Colorado, have inventedcertain'new and useful Improvementsin lVindow-Shades, of which the following is a specification.

This invention relates to window-shades and its primary object resides'in providing a shade of simple and duiuble construction which by readily effected adjustments may be raised or lowered to cover or uncover any portion of a window to which it is applied, without the use of rollers or other winding devices.

I attain this object by the use of a shade composed of a series of lapping slats which are interconnected by flexible tapes to permit of their sliding upon each other for the purpose of folding the shade while it is be ing raised or lowered. V

The flexible bands are attached at their lower 'ends preferably through the medium of the lowermost slat, to a holder adapted to receive the slats in their folded condi- A cord fastened to the'uppermost slat of the shade is trained over a series of pulleys or other suitable guidingdevices at the top of the window-frame to raise the upper end of the shade, and a pair of cords attached to the holder are likewise trained over pulleys at the upper end of the window-frame for the purpose of raising the lower end of the shade when it is desired to uncover the bottom portion of the window.

Cleats fastened at opposite sides of the window are provided to attach the cords for the purposeof securing the shade in its adjusted positions.

An embodiment of my invention is illustrated in the accompanying drawings in the various views of which like parts are similarly designated, and in which Figure l is a face View of my improved window-shade in its operative position in front of a window, I

Fig. 5, a sectional View of the slats showing their relative positions when bunched within the holder, and

Fig. 6, a longitudinal section'through a portion of one of the slats to better show the construction of the clips by'which they are fastened to the tapes. i

The reference character 2 designates the frame and?) the sash of a-window of ordinary construction. 1 1

Myimproved shade is composed of a series of oblong slats l made of cardboard, wood or any other suitable substance and interconnected by two parallel tapes 5 of webbing or other flexible material.

The slats are secured to the tapes byineans of normally U-shaped clips 6 which embrace the tapes with their ends passing through openings in the slats at opposite sides of the tapes and bent against the back of the same.

- The upper slat of the series is reinforcedalong its upper edge by a strip 7 of wood or other suitable material and the lower slat of the shade is rigidly. secured to the holder 8 in which the slats are received when either the upper end of the shade is the lower end of the same is raised. l

The holder in its preferred form as shown in the'drawings, is composed of two U- shaped stirrups 9 rigidly connected by two parallel bars 10 preferably made of wood.

The lowermost slat of the shade is rigidly fastened to the holder by bending the ends of the forward portions of its U-shaped members over and upon the upper edge thereof, as best shown in Fig. 3 of the drawings.

The adjustable suspensionof the shade .in front of the window-sash is eflected through the medium ofa number of pulleys which are attached to the upper transverse portion of the window-frame.

These pulleys maybe of any convenient construction suitable for the purpose and if used in connection with shades of small dimensions they may consist of screw eyes such as have been shown in the drawings.

A cord 12 fastened in the middle of the reinforcing strip of the upper slat is trained over pulleys 13 and 14 and normally fastened to a cleat 15 applied to the windowframe at a side of the window.

" Apair oflcords 1 6;are fastened to the up per ends of the :rearmost arms \of the U- shaped members ofthe holder-8 and trained over pulleys 1-7, 18 and 19;

The two ropes areunitedatapoint 20 and normally attached to a cleat 21 at the a side ofthe windowopposite to that at which 'thefirstnnentioned-cleat is fastened.
